Buratex W 4003


Buratex B 4003 is a flexible cotton packing impregnated with a special light-colored grease impregnating agent. It is preferred for pure, liquid media and clean applications. When it is manufactured, particularly tear-resistant cotton threads are pre-impregnated and twisted. At the next diagonal braiding step, the packing undergoes an additional intensive impregnating stage.


  • Easy to handle
  • Rot-resistant
  • Permanently soft and flexible
  • No risk of discoloring the medium

Operating range

Pressure: p = 10 bar
Sliding velocity: vg = 10 m/s
Pressure: p = 60 bar
Sliding velocity: vg = 2 m/s
Mixers, agitators, kneaders, filters
Pressure: p = 8 bar
Sliding velocity: vg = 2 m/s

  • Continuous operation:
    t = -20 °C … +100 °C

Chemical resistance:
pH = 6 ... 8
Resistant to water and waste water, particularly resistant to oils and greases.


In pump applications, ideally fitted with a straight cut. The light-colored impregnation avoids any risk of discoloring the medium.
